DNA and forensics help?
1.)A large portions of any single person’s DNA are the same as every other person’s cause we’re all human. (example : we have skin not scales) 2.) But there are fragments of our DNA which are unique called polymorphic (meaning they vary in shape from person to person). So, DNA profiling is the process of separating an individual’s unique, polymorphic, fragments from the common ones and then analysing them.
